Anyhow, I spent most of last week in Pittsburgh having medical appointments and meeting with various people (professors, administrators, fellow grad students). Kristen was kind enough to put me up in her spare bedroom, and even picked me up at the airport and dropped me off at the train station. You can read Kristen's report on the Pittsburgh basics, complete with a photo of her street and house, at Procrastinating in Pittsburgh: Pieces of Pittsburgh. This certainly makes up for my failing to take any photos of Pittsburgh while there, or so I like to imagine.
My advisor, who rose from her sickbed to ply me with gin (well, this is a mild exaggeration but not entirely false), seemed generally pleased with my report of last year's research and recommends that I go ahead and spend all of this year in Prague unless there is some burning reason to do otherwise.
Since my brain aches and I still have to figure out my transportation to the aforementioned conference, I shall say no more for now.
